构建新项目时，Java项目语言级别会自行更改-IntelliJ

Question

Whenever I build a new project the project language level is automatically changed on it's own down to 6. Which means that whenever I try to build the project I get errors and warnings etc. I have been trying to change the project defaults but this does not help. I have also attempted to set the byte code version as 9 by default.

This is my Project Structure before I set up a new project:

After applying these settings I create a new hello world (console) application. I then run the project and get these errors:

The only code in the main class is `public class Main {

public static void main(String[] args) {
    System.out.println("Hello, World");
}
}

`

I then go and check the project structure and see that the project language level has been changed. Why is it doing that and how do I stop this from happening? I have been researching this problem and even contacted the JetBrains forum but nothing helps. + I have also attempted to set the 'project byte version' as 9 by default but this also gets changed after I create a new project.

This is what project structure looks like after running the project:

During my research I found out that if this is a maven project you can fix this by changing the pom.xml file but this is just a java console application.

These are the java compiler settings:

FYI by default it is set to 9; when the project is created it is set to nothing.
